Airbag(Event #1)
B135500 Passenger Airbag Resistance Circuit Short to Battery (1st Stage) - General Information

Component Location





General Description

Passenger Air bag module (hereinafter referred to PAB) located at passenger side crush pad protects passenger by reducing impact of collision.
This PAB contains 2 firing squibs of airbag and 1 firing squib of active vent.
Depending of crash speed or the tightening of seat belt, it is decided a timing about both 2 firing squibs of airbag and 1 firing squib of active vent.
At the moment of vehicles collisions, the firing squib of active vent make airbag distended and then consecutively leaked gases of airbag through a hole at once.
These operations reduce a injury of passengers head.

CAUTION:
Never measure resistance of PAB directly, Current of measuring device may cause unexpected air bag deploy.

DTC Description

The SRSCM sets DTC B135500 if there is a short to power in PAB harness.
*In this case, SRSCM checks if there's any fault in circuit by sending current for a while.
